The primary lobject ofthe inventionis the.

provision of a bomb thrower adapted'for operation without the employment off-explosives whereby @missiles may be hurled great distances with only slight expense.

A further object of theinvention is the provision of a device for throwing missiles that is easy and inexpensive to manufacture v arranged for adjustment whereby the distance .to which. the missiles are' thrown may l be regulated, the throwing operation being readily set by soldiers in charge of the dev icedand tripped at any distant point desire plication-f and in which like numerals refer to corresponding parts throughout vthe several views:- l I Figure 1 is a central longitudinal vertical sectional view of the device;

Fig. 2 is a side elevation thereof with a side portion thereof broken away andthe mechanism 'arranged in its tripped position;

Fig. 3 is a top plan View of the device arranged as shown in Fig. 1; and

Fig. 4 is a vertical transverse sectional view taken upon line 4--4 of Fig. 1.

Referring more in detail to the drawing, the device comprises opposite sides 10 connected together b spaced rollers 11 and 12 journaled throu the said sides while oppositely inclined toes 13 are carried by the sides 10 adapted to project into the ground 14 for anchoring the device in position'when desired for use.

An arm 15 is secured to and radially pro-v jects centrally from the roller 12 having a receiving socket 16 in the enlarged head 17 thereof adjacent the free end of the said arm while curved prongs 18 are carried by the head adjacent the said socket for con-.

venience in positioning a missile or cannon ball 19 withm the socket.

An operating spring 20 isconnected centrally to the roller 11 at the point 21 and is adjustably attached to the arm 15 by means of an -bo1t 22. VIt will be readily seen that Specica'tion of Letters Patent.

by positioning the ball 19 within the socket 16 and rearwardly depressing the arm head 17 as shown in Fig. 1 of the drawing, the spring 20 will be placed under tension and upon releasing the arm 15,' the arm will swin forwardly for hurling the ball 19 in the ing the bolt 22 longitudinally of the arm 15 whereby the length of the spring 20 will be esired direction. The tensionof the Y spring 20 may' be slightly adjusted by movregulated when the device is set so that the lthrowingdistance may be slightly altered in this manner.

A cross bar 23 is arranged between the sides 1,0 adjacent the rear end of the device with a spring 24 centrally mounted thereon u on which the arm 15 is adapted to seat W en inits set arrangement while a hook 25 serving as a trigger is pivotedat 26 to the bar 23 with its retaining end 27 engaging a keeper 28 upon the bottom of the said arm. By this means it will rbe seen that the arm 15 is swung rearwardly and depressed upon .the spring 24 which will retain the trigger 25 in engagement with the keeper 28` when the device is set and until released by pivotally moving the trigger 25 in any desired manner such as by pulling upon the'fring cord 29 attached to the lower end of the said trigger. The spring 24 also acts to assist4 the initial upward and forward swinging movement of the arm 15V during the operation-of the device assisting the spring 20 at such times when the spring 20 is arranged in a plane approaching that of the plane of lthe arm 15. 4 The soldiers in charge of the device can manually depress the arm 15 and set the.

same with the trigger 25 in .its engaging position and a ball 19 or other missile may be then positioned within the socket 16. The cord 29 maybe grasped and pulled for releasing the trigger 25, permitting the spring 20 to operate the arm 15 and hurl the ball 19 as found desirable. The position of the device as a whole will be maintained normal by the engaging toes 13 of the side members 10. The device possesses great simplicity and is subject. to little wear during opera-v tion while the length of its throw may be regulated by adjusting the bolt 22. It will ici also be evident that other forms of missiles than the ball 19 may be hurled by means of the device such for instance as explosive bombs or hand grenades.

llllO 1. A throwingldevic'e comprising a mounting means, para el rollers carried thereby a missile-supporting arm carried by one of tlie rollers, an operating spring secured to the other roller and adjustably 'connected to the said arm whereby the tens1on of the spring .is

saidarm whereby the tension of the spring is adapted for regulation when the arm is in its set arrangement prior to the operationy of the device, seatin means for a4 missile arranged upon one si e of said arm, a keeper upon theother side of the arm, a swinging trigger carried by the supporting gaging the said keeper when the evice is set, and resilient shiftmg means Jfor the arm adapted for contacting the arm at a point adjacent vthe said keeper.

3. A missile thrower comprising opposite parallel sides, anchoring toes inclined in opposite directions from the lower edges of said sides, transverse rollers 'ournaled in spaced relations in the said si es, a missile hurling arm radially projecting centrally of the rearmost roller aving an enlarged head portion at its free end wlth a socket in its forward face, missile-seating prongs carried ating sprin means en".

' recense bysad head adjacent the socket, an I-bolt connected between the other roller and the said I-bolt, and retaining means for the arm -when in its rearwardlylowered set arrangement.

4. A missile thrower comprising opposite paralleli'sides, anchoring toes inclined in opposite directions from the lower edges of said sides, transverse rollers spaced relations in the said si es, a missile hurling 'arm radially projecting centrally of the rearmost roller having an enlar ed head portion at its free end with a soc et in its forward face missile-seating prongs carried by Said head adjacent the socket, an I-bolt carried by the arm adjustably arranged longitudinally of the arm, an oper connected between the other roller and t e said I-bolt, a transverse bar arran ed between the sides adj aoent the rear end o the device, a verticall positioned coil spring arranged-upon the ar upon which the said arm 1s its depressed rear position, and a releasing cord or the trigger attached to the lower end thereof and extending a distance rearwardly of the device.
